SPECIFICATION forming part of Letters Patent No. 240,547, dated April26, 1881.

Application filed July 29, 1880. (No model.)

To all whom it may concern:

Be it known that I, GEORGE RIEsEcK, of

Allegheny, in the coun tyofAlleghen y and State of Pennsylvania, haveinvented certain new and useful Improvementsiii Meat-Choppers; and I dohereby declare the following to beafull,c1ear, and exact description ofthe invention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

My invention relates to an improvement in meat-choppers; and itconsists, first, in placing the boxes for the cranked driving-shaft 1 5upon a vertically-movable rod, and guiding the boxes in their movementsby means of slots in the frame, and attaching the pitmen for operatingthe cutters, and the valve-rod to the cranked shaft, so that when theshaft is raised upward the machine will be stopped; second, in thecombination of the cranked shaft having a vertical movement, the pitmenwhich operate the cutters, the valve-rod and valve, which are operatedby the shaft, a valve for controlling the admission of steam to thesteamchest, and which valve has a rod attached to it for passing upthrough a frictional stuffingboX, with the tub, cutter, and frame,third, in the combination of the cranked shaft, which is journaled upona vertically moving bar, connecting-links, and levers which are pivotedtogether at their inner ends and to the frame at their outer ends withthe pitmen, cutters,

and tub; fourth, in the arrangement and com 3 5 bination of parts, whichwill be more fully described hereinafter, whereby the driving mechanismis thrown in and out of gear with the revolving rack upon which the tubis placed.

The accompanying drawings represent my invention.

Figuresland2 are side elevations of myinvention. Fig. 3 is an invertedview of the same. Fig. 4 is a vertical section taken through the frame.Fig. 5 are detail views of the valves.

4 5 Fig. 6 is a side elevation.

The frame A consists of the standards a, braced by I), cast with theformer, having braces 11, b and 11 between them.

Between the sides of the frame A, near the '50 bottom, are thehorizontal braces d, which support the meat-block B upon rollers inadvance of the standards a.

Under the block'B, and attached thereto, is a rack, 00, that is engagedby a pinion, D, rotated by a pulley, E, on the end of its shaft, outsideof the frame A. The shaft of this pinion moves in a sleeve, 6, to whicha lever, f, whose fulcrum is on the inside of the frame A, is attached.The handle of the lever f extends forward, and if depressed raises thesleeve and pinion, engaging thereby the rack under the meat-block; butwhen raised up it throws the pinion out of gear, whereby the rotation ofthe block is stopped. Between the lever f and the inside of the frame Ais the guide as, with shoulders that limit the up or down motion of thelever; and pivoted on it is a dog,g, which, when the lever is depressedand the pinion in gear with the bevel-wheel, catches on top of atriangular block, it, near the handle of the lever, and prevents it fromrising; but when the pinion is thrown out of gear, by raising the leverthe dog catches under the block h and secures it in that position. Bythis means the meat-block may, for any purpose whatever, be stopped,turned back or forward, and again set in motion by hand while the engineis running.

In the standards a, between the braces b and 15 are slotsi, in whichrest the ends of a flanged bar, 0, and under the slots, 'at the insideof the standards, are vertical guides K,in whichthe ends of the flangeunder the bar Gare confined. On top of the bar, at its ends and in themiddle, are pillow-blocks N, in which the crank-shaft F is journaled.The ends of the. crank-shaft protrude beyond the standards a, and on oneof them is a belt that runs the pulhey E, and on the other is thefiy-wh'eel G.

Thepitmen w on the crank-shaft are rigidly attached by wrists tovertical rods Z, that have their lower guides on a brace, m, between thestandards, and at their upper ends to the slides a, in front of theupper cross-piece connecting the standards.

From the attachment of the pitmen to the vertical rods lforward, extendthe-arms at a right angle with the rods. The arms are supported bybraces attached to the slides n, and to or near the outer ends of thearms p, 100

thus forming a rectangular triangle over the meat-block. The knives Hare adjustably attached to the forward ends of the arms 1), and

are raised or depressed by the rotating crankshaft.

One (or both) of the rods 1 is prolonged upward beyond the slides a, andacts as a pistonrod to the steam-cylinder P, placed on top of the upperbrace, between the standards a.

At the side ofthe cylinder is a steam-chest. S,into which enters,frombelow, the valve-stem U,joined to a cam-rod on an eccentric of thecrank-shaft F. The valve-stem U operates the slidingvalve within thesteam-chestin the usual manner.

Steam is admitted into thechest through a valve, q, attached to thechest, which valve is operated by the rod 0), that is brought in contactwith it when the crank-shaft is lifted up from its ordinary position.

On top of the valve (1 in the valve-chamber is a rod, 1, which passesout through a stuffing-box, and holds the valve when it has been pushedup by the rod underneath the valve in that position. The steam is shutoff when the valve "is pushed up, and the friction on the rod in thestuffing-box keeps it from reopening itself, and will have to be pusheddown by hand to read mit steam.

The valve q, with its rod 1", may be placed in nected with thecrank-shaft are raised up and the valve admitting steam is closed. Thusthe machine is brought toa standstill, when a continued motion wouldunavoidably cause some of its parts to be broken.

To prevent an oblique o r unequal motion of the bar 0 when only one ofthe knives meets an impediment, a pair of links, t, are jointed to theflange under the bar, which links form fulcrums to two levers, J, thatare pivoted to the insides of the standards a. The ends of the, leversmeeting at the middle, under the bar O,'are joined together, and by thisdevice the motion of the bar, be it rising or falling, is made to bealways horizontal.

The object of my invention is to prevent oil, grease, or dirt, fromfalling on the meatblock and being chopped with the meat, by placing allparts of the machinery employed to operate this meat-chopper away fromover the meat-block. Many of the meat-choppers now in use have a greatpart of the working machinery immediately over the meat-blockandknives,anditis consequently nexttoimpossible to prevent things frombecoming mixed in with the meat that should be kept separate from it.The automatic action of the valve, whereby the steam is cut off at amoment when continued motion would inevitably cause some part of themachine to be injured, I also consider of importance. An advantage isfurthermore gained by the use of the lever and dog, since by stoppingthe rotating block access to it is obtained, whethcrto clean its surfaceor for other purposes.

Having thus described my invention, 1 claim 1. In a meat-chopper, thecombination of the frame provided with guiding-slots, the crank-shafthaving its ends journaled in boxes which move in slots, the bar (J,having the boxes or bearin gs for the shaft secured to its top, thepitmcn for operating the cutters H, the slide-valve, valve q, theoperating-rod 'v, and the tub in which the meat is cut, substantially asshown.

2. In a meat-chopper, the combination of the cranked shaft F, having avertical movement, the pitmcn w, for operating the cutters, and thevalve-rod 11, attached to the shaft, with the valve q, rod r, andstuffing-box, tub. cutters, and frame, the parts being combined tooperate substantially as described.

3. In a meat-chopper, the combination of the links t, levers J, pivotedto the'frame at their outer ends and to each other at their inner ends.with the vertically-moving bar 0 and shaft F, mounted thereon, pitmcn,cutters, I00 and tub, substantially as set forth.

4. In a meat-chopper, the combination of a revolving rack upon which thetub is placed, the pinion D, placed on the same shaft as thedriving-wheel E, with the sleeve 0, lever f, dog g, and guide 00,substantially as shown.

In testimony that I-claim the foregoing I have hereunto set my hand this24th day of June, 1880.

GEORGE RIESEOK.
